Creating Filmless Motion-Picture Mattes on the LaserMatte System

Craig Witty

An imaging system has been built that provides a method for creating and combining images on motion-picture film without resorting to the use of either film-based mattes or video compositing techniques. The LaserMatte system produces a very high resolution image on a tungsten-illuminated laser-addressed liquid crystal light valve. The image on the light valve acts as an articulate printing light, which selectively exposes the film frame. Consequently, the problems associated with producing and realigning color-separation-based film mattes are circumvented. Because the system is capable of creating mattes, it also avoids the disadvantages inherent in video- and computer-based electronic imaging systems that must convert all image information to a video signal.
